The named steel sections in FERS Cloud and in the FERS Python package come from the sources below. Section dimensions and properties are published engineering data. If you hold rights in any of it and object to its use here, write to legal@ferscloud.com and we will remove it.
- British Steel — UK sections
- Section data: British Steel. Dimensions and properties to BS EN 10365:2017. Used with permission. Copyright British Steel 2026.
- UB, UC and PFC sections, from British Steel's UK sections datasheets (CUBD, CUCD and CPFCD:ENG:072026).
- Used with permission: British Steel confirmed in October 2026 that the data is free to use with attribution.
- British Steel — ASTM sections
- Section data: British Steel, ASTM sections datasheet. Copyright British Steel 2026.
- W and HP sections that British Steel rolls, from its ASTM sections datasheet (CAWSD and CAHSD:ENG:072026). A starred weight is marked on the datasheet: “Non-ASTM weight, but still offered by British Steel.”
- Covered by British Steel's general reply that its data is free to use. Our request named the UK sections, not this datasheet.
- AISC Shapes Database v16.0
- Section data: AISC Shapes Database v16.0, American Institute of Steel Construction.
- US W and HP sections that British Steel does not roll, rectangular and round HSS, and pipe.
- Used without explicit permission, as published dimensions and section properties. We will remove it on request.
- European sections
- Standard dimensions (EN 10365:2017, EN 10210-2); section properties computed by FERS from those dimensions.
- IPE, HEA, HEB, HEM, UPE, CHS, RHS, SHS and L sections.
- No third-party property table is reproduced.

Where we differ from the datasheets
Four misprints in British Steel's datasheets are corrected rather than reproduced. Each one disagreed with the section's own mass, its other printed values, and the same section on the other datasheet:
- UB 406x260x132 and W16X89 (the same section): web printed as 16.3 mm. It is 13.3 mm, and the area, second moments, moduli and torsion constant computed from it are corrected with it.
- W27X94: web printed as 21.4 mm. It is 12.4 mm, with the properties computed from it corrected likewise.
- W16X100: minor-axis radius of gyration printed as 2.38 cm. It is 6.38 cm.
- W16X67: minor-axis second moment printed as 4995 cm⁴. It is 4955 cm⁴.
The UB 406x260 series is printed as 410x260 on the datasheet's properties page. FERS uses 406x260, the designation on its dimensions page.
